Medical Xpress / More screen time in childhood associated with better cognitive processing in adolescence
In a study conducted at the Universities of Jyväskylä and Eastern Finland, more screen time since childhood was associated with better cognitive processing in adolescence. According to one of the researchers, we should not ...
Phys.org / Late Paleozoic Ice Age warming event hints at potential climate 'tipping point'
Researchers say a spike in temperatures during an ice age 304 million years ago could inform what climate scientists are learning about rapidly changing conditions today.
Medical Xpress / Long before adulthood, a chemical mark may quietly shape how the brain handles stress
Stress or trauma during childhood may leave people more vulnerable to mental health struggles and stress later in life. Scientists think one reason could be that early-life stress leaves lasting molecular bookmarks on DNA, ...
Phys.org / Bumblebees can learn to associate new smells with their queen
Bumblebees are able to learn to associate new odors with their colony's queen, instead of being preprogrammed to recognize the queen's pheromones from birth, according to a new study led by researchers at Penn State. For ...
Medical Xpress / Sleep could help identify people at risk of developing Alzheimer's disease at an earlier stage
What if certain signs of the disease were to manifest subtly during sleep, long before the first memory problems appear? This is the line of inquiry being explored by a team of researchers at ULiège.
Phys.org / How to design a space habitat that supports its residents' mental health
In extreme environments, habitats are built for survival. Submarines, Antarctic bases and post-disaster dwellings are designed to prioritize health and safety. This is especially the case for habitats in space, where room ...
Phys.org / Want a happier marriage? Study suggests one simple habit
Research has long shown that exercise benefits both physical and mental health. Now, a new study from researchers at BYU suggests that it may also strengthen marriages, especially when couples exercise together.
Medical Xpress / Machine learning approach could bring greater certainty to prenatal genetic testing
Advances in genome sequencing are giving more families access to prenatal genetic testing and new information about an unborn baby's health, including whether genetic changes may be linked to a neurodevelopmental condition.
Phys.org / Early snakes explored life underground, on land and at sea
Snakes are highly modified lizards, with more than 4,000 living species today. The origin of snakes has long been one of evolutionary biology's most debated questions. Their sparse fossil record has made it hard to pin down ...
Medical Xpress / New miniature microscope allows scientists to watch and control brain cells during natural movement
Researchers at the University of Colorado Anschutz and the University of Colorado Boulder have developed a miniature microscope that allows scientists to observe and activate individual brain cells during natural movement, ...
Phys.org / Mitochondrial proteins may trigger inflammation by mimicking bacterial distress signals
Mitochondria are often called the powerhouses of the cell. But their ancient origins may also make them drivers of inflammation. Researchers at the University of Illinois Chicago have discovered that proteins released from ...
Medical Xpress / 3D lifespan map suggests mouse ovaries keep a constant share of eggs primed
As mice age, their total egg reserve collapses around tenfold. Yet, according to a new study published in Nature Aging, the proportion of eggs in the brief window where a follicle is shifting from dormant to growing stays ...
